Crypting/ciphering or wtv it's called will only fool the hash checks Nexon does. Certain parts of the hack may still be detected and if this is the case, it would result in crashes midgame without any resulting action like a ban. Skater is most likely right and as you don't seem to be a coder yourself, may I suggest next time you listen to what others has to say instead of putting your trust into some sort of tool someone else made.
